The Linshang LS170 is a portable, app-connected colorimeter designed for measuring and comparing color of materials accurately — especially useful when visual assessment isn’t enough (e.g., printing, coatings, packaging, textiles, plastics).
🧪 Key Features
📍 Portable & App-Driven
Works with the LSColor mobile app via Bluetooth — measurement results appear directly on your phone.
🎨 Color Measurement & Matching
Measures color in multiple color spaces:
• CIE Lab, Luv, LCh, Yxy, CMYK, RGB, Hex.
Includes built-in color reference charts; can match the closest color codes (≈90 % accuracy) and build your own color library.
📊 Color Difference & Quality Control
Supports multiple color difference formulas (e.g., ΔEab, ΔEuv, ΔE94, ΔEcmc formulas, ΔE*00).
Offers a quality control mode where you can set a tolerance threshold and quickly judge whether a sample color is acceptable.
🔄 Good Repeatability
Repeatability (standard deviation ΔE*ab ≤ 0.03) — indicating stable, consistent readings after calibration.
🔋 Long Battery Life
Rechargeable lithium-ion battery — about 10, 000 measurements per charge.
USB-C charging.
